Second Life. Have any of you played it?

I was looking up on the game Second Life. It looks like one of those games I'd probably get addicted so I kind of steered clear of it. Do any of you play it? Do you download the game off the site? What are the fees in the game? It seems like there's a monthly fee and fees if you want to buy additional things but I was confused. Let me know! :D

I play Second Life sometimes. You can download the game & start a basic account for free. You can earn Lindens, the SL currency, in the game by making and selling stuff, or by providing services. If you want to own land in the game, you need to upgrade to a premium membership. That costs about $10 a month.
I have not gotten a premium membership yet, and have not spent any of my own money to play in the game or to get anything in it.

hello! I discovered only today Second Life!
I think it's a nice game...in wich you can meet new people or just enjoy and explore all that "universe". It's strange to walk or fly (yeah you can fly there too) or drive a car inside that game, and others will see you doing things.
You can buy things or make them...i am curious about making new things and selling them....is there a way to earn some money there? I will try it!
Maybe I could play there with my earnings of myLot :-)
